The idea of “pops” in EU IV/V seems to have a lot of supporters. The below is absolutely not intended to make a point, but is intended as an open question. That said, an overhaul to allow more of a focus on building your economy in a more detailed way in peacetime would be nice. What's worse is that if you are expanding fast and constantly into a religion it may come a point where you are getting more AE than you can ever burn, even if it is just 1 or 2 AE here and there.Ĭountries joining in mass can happen when you are at war because coalitions take the military force of your war enemies as if it was part of the coalition when calculating if they should join the coalition and/or declar a punitive war against you.I’d hope that EU IV will carry on a while yet. It is very easy to accrue AE with half, if not all, of the Islamic world because AE take religion into consideration. To address OP's point, that's just how Muslim nations roll. Similarly, you can inadvertently trigger a coalition by restarting the game if you have a bunch of countries with 50+ AE that for whatever reason haven't had their attitude towards you recalculated.

That's why one of the tips for managing coalitions is to always restart your game if you think that a coalition should have already disbanded but it didn't. By restarting the game your force it to recheck for AI attitude and it goes from hostile to neutral (because it meats the criterias for doing so).

Why? Say a nation is over 50 opinion of you but if currently hostile. When you restart the game it forces a recheck on a bunch of AI behaviour (and some other stuff) which can lead to countries leaving coalitions.
